Set Dir to reverse the direction of the motor. The motor decelerates, stops and
then accelerates in the opposite direction. The FA1 bit clears as soon as the
reference frequency is changed. Once the new reference frequency is
reached, the FA1 bit is once again set.
Clear the Opr bit to stop the motor. The motor decelerates and comes to a
halt.
User trips can be generated by setting the EXT bit in coil data 0. You must
always immediately clear the Opr bit in your PLC program when the Unit indi-
cates it is in Trip status (for example when AL bit is set ON). If the Opr bit is set
when the trip condition is cleared, the Inverter will immediately start running!
Always clear the Opr bit in your PLC program when the AL bit is set ON by the
Inverter. Not doing so may result in the motor starting unexpectedly when the
trip is cleared.
Set and clear the RS bit in coil data 0 to clear a trip.
Always clear the RS bit after setting it. Not doing so will result in new trip con-
ditions automatically being cleared.
